VALVE.

SPECIFICATION forming part of Letters Patent No. 543,274, dated July 23,1895.

Application filed Tune 18, 1894. Renewed May 27, 1895. Serial No.550,871. (No model.)

To ctZZ whom it may concern.-

Be it known that I, GEORGE F. SPEER, a citizen of the United States,residing at Tyler, in the county of Smith and State of Texas, haveinvented certain new -and usefulIm- .provements in Valves; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

My inventionhas relation to valves; and it consists of a new valve andnew valve-seat constructed substantially as shown in the4 accompanyingdrawings, in which Figure l is a side elevation of the valve,

partly in section, showin g my valve and valveseat in section. Fig. 2 isan edge view of the valve, partly in section, showing my valve andvalve-seat in section, also the lever and lever-rest. Fig. 3 is an edgeview of the lever.

My invention is described as follows: A represents the shell of thevalve; B, the

' guide and cap; C, the stuffing-box nut; d, the

valve proper; e, the stuffing. f is the neck of the Vvalve running upthrough the guide and cap B, stuffing-box nut C, and against the lowerface of the stern-nut g, which nut holds the valve down solidly againstthe upper face of the shoulder h of said valve-stem. Said valve-stem iextends entirely through the valve body and has on its lower end nuts jjto regulate the pitch of the valve-lever k.

In the shell A is my tempered-steel or other hardmetal gable-shapedvalve-seat Z, and in the lower face of the valveis my removable softcontact-ring m, which may be made of brass or other material, in whichthe edge of my tempered-steel or other hard-metal gable-shaped seat maycut a water-tight lit.

The features of my invention which I claim as new and novel are: Mytempered-steel or `other hard-metal gable-shaped seat Z, that can beremoved and replaced when it begins to valve to seat and prevent it fromcooking, the valve-joint being made by the brass ring fm, being pushedhard down on the temperedsteel seat, causing an impression of-seat to becut in the brass ring of valve, the face of the seat being on line ofbottom of'inlet to valve, which forms virtually a straightway valve.

By the seat being of tempered steel or other hardened material,`joint isnot made by two perfect faces in contact, but by hardened seat cuttingin the softer ring i'n valve.

Having described my invention, what I claim as new, and desire to securebyv Letters Patent, isi 1. The combination of the shell A, provided'with the usual water-inlet andowater outlet, vand perforation for thevalve stem to work -passing up through guide and capB; soft contact ringm, fitted in the face of the valve "d, and adapted to come incontactwith the edge of the gable-shaped seat Z; guide and cap B,fitting on the upper part of said shell; Vstuiiin,; ,'-b0x nut C,fitting on the upper end of said guide and cap; and stem nut g, workingagainst the upper end of the neckf, and holding the valve d, rmly andsecurely against the upper face of the shoulder h, substantially asshown and described and for the purposes set forth.

2. In a valve, substantially as shown and described,'the valve CZ,provided withz a hollow neck f, adapted to work up and down through theguideB, and stuffing-box nut C; rod c', 'running through said valve d,and holding said valve firmly between its shoulder h, and nut g,vsubstantially as shown and described and'for the purposesy set forth.

In testimony whereof I affix my signature in presence of two witnesses;

GEORGE F. SPEER.
